What does "pH" measure in the context of water quality?

The term "pH" specifically measures the acidity or alkalinity of water. The pH scale ranges from 0 to 14, with values below 7 indicating acidity, a value of 7 signifying neutrality, and values above 7 denoting alkalinity. This measurement is crucial in assessing water quality since it affects the solubility of nutrients and minerals, as well as the biological activity within aquatic environments.

Understanding pH is essential for maintaining water systems because it impacts everything from the health of aquatic life to the effectiveness of water treatment processes. For example, certain plants and aquatic organisms have specific pH requirements for optimal growth and survival. Therefore, maintaining the appropriate pH level in water can significantly influence overall water quality and ecosystem health.
